Nano-indentation 실험과 유한요소 해석을 연계한 재료의 탄소성 물성 평가법 개발
A Method to Estimate Tensile Properties using Combined Nano-Indentation Tests and Finite Element Simulations
초록
Determination of elastic properties of nano-scale materials using nano-indentation tests is well established, but that of plastic properties is not yet clear. This paper presents a method to extract plastic properties from nano-indentation test, together with results from detailed elastic-plastic FE analysis. It shows that the plastic properties determined from this method are not unique, in the sense that a number of different plastic properties can give the same load-displacement response from nano-indentation test. possible ways to overcome such problems are discussed.
